INK-FOUNTAIN;

SPECIFICATION forming part'of Letters Patent No. 258,290, dated May 23,1882.

Application filed August 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALFRED GAGE, of the city and county of Philadelphia,Pennsylvania, have invented, made, and applied to use Improvements inthe Construction of Ink-Fountains for Job-Printing Presses; and I dohereby declare that the following is a full, clear, and correctdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, said drawingsforming a part of this specification, in which-- -I igure 1 is a topView of myimproved fountain. Fig. 2 is alfront elevation of the same.Fig. 3 is a perspective view of the same. Fig. 4 is a view of thefountain with the duct-roller thrown back for cleaning; Fig. 5, a viewof the fountain as applied to a job-press.

In the drawings like parts of the invention are designated by the sameletters of reference.

The nature of the present invention relates to improvements in theconstruction of inkfountains for job-printing presses; and it consists(a) in the combination, with the well or trough of an ink-fountain, of aduet-roller supported by hinged arms, so that the duct-roller may beturned back when desired and access be had to the trough or well; (b) inthe combination, with the fountain, of the means employed to give aforward and backward movement to the same; (0) in the combination, withthe fountain, of the means employed to raise or lower the same asdesired.

To enable those skilled in the arts to make and use my invention, I willdescribe the same.

My invention is intended particularly to ap ply to that class ofink-fountains used in connection with job-printing presses in which arevolving disk or table is employed to distribute the ink by the passageof the form-rollers over it, the ink being supplied to these rollersfrom the fountain, and in Fig. 5 of the drawings the fountain is shownas attached to a press of this eharaoten the revolving table beingdesignated as A an the brackets supportin g the fountain as B, thesebrackets held in any convenient manner upon the cross-brace or saddle Csupporting the table, and made of suitable length to bring the fountainat the rear of the table, or in a suitable'position for the form-inkingrollers, as they reach the extent of their upward movement overtheta-131e,, to be brought into contact with the duct-roller D of thefountain and be charged with ink by the same.

E shows the trough or receptacle for the ink, constructed with aninclined bottom, and D is the duet-roller, placed directly in front ofthe trough or receptacle E. The ends of this ductroller D are providedwith the spindles F, passed through openings in the forward ends of thearms G, the rear ends of which are swiveled to the sides of the troughor receptacle E. In the upper sides of these arms G, back of theduct-roller, are inserted the set-screws H, free to engage with threadedopenings in the lugs it upon the front of the trough E, so that bymanipulating these screws H the duct-roller can be raised or loweredrelatively to the bottom of the trough or receptacle, and thus governthe flow of ink to the duct-roller from the trough. Upon one of thespindles is secured a ratchet-wheel, I, with which apa-wl, J, hung in anarm, L, engages, and by connecting this arm L with the roller-carriageof the press, so that movement is impossible to it, the'pawl' engageswith the ratchet-wheel, and by causing the same to revolve a certainextent with each movement of the roller-carriage the ductroller iscaused to revolve a certain extent and present a fresh supply of ink tothe form-rollers.

Iprovide, in connection with the fountain, means by which it may beadvanced or withdrawn in a right line, and also by which its positionvertically may be determined. The first means may be thus described: Thetrough has upon its rear the ears or lugs M, having threaded openings.Over these lugs or cars are passed the hollow plates N, provided withopenings in line with the threaded openings when the plates are passedover the lugs or cars M. Through these openings the regulatin g-screwsenter and engage with the threaded openings in the lugs or cars M, andby advancing or withdrawing these screws 0 the position of the fountainin a right line is Varied as may be necessary to adjust the front orforward end of the fountain to the form-rollers, the movement of whichvaries on presses of 2 eaaeeo different construction, and thisadjustment is necessary that the form-rollers may be brought intocontact with the duct-roller. ain is adjusted vertically by means of the5 threaded standards P, supporting the plate N, and supported inbrackets 13 by means of the threaded collars R, which turn on standardsP. The brackets B have a smooth bore large enough to permit thestandards P to move freely up and down in them as the collars R areturned. When the collars are turned so as to rise on the standards thefountain descends by its weight, and when the collars are screwed downthe standards rise and raise the 15 fountain, the collars R resting onthe top of brackets B.

As the composition rollers in use are subject to more or less shrinkagewhile in use, this adjustment compensates for the same and allows thefountain to be adjusted to the same.

The operation of the invention may be thus set forth: The trough orreceptacle is filled with ink. Its flow to the duct-roller is regulated,as already set forth, by adjusting the duet-roller in position to theink-receptacle, and the rotation of the duct-roller with each movementof the roller-carriage gives afresh supply of ink to the form-rollers,by them to be supplied to the revolving table.

The fount-.

The ability of the operator to govern the forward and backward movementof the fountain, as well as its vertical movement, will be foundadvantageous, while the hinging of the ductroller supports enables allparts of the fountain to be easily got at for cleaning.

Having now described my invention,I claim as new 1. The combination,with the trough or receptacle E, of the duct-roller D, hinged arms G,and regulating-screws H, constructed and operating substantially as andfor the purpose specified.

2. The combination, with the trough or receptacle E, of the lugs M,hollow plates N,and regulating-screws O, constructed and operat ingsubstantially as and for the purpose set forth.

3. The combination, with the trough or receptacle E, of the threadedstandards P, brackets B, platesN, and threaded collars, substan- 5otially as and for the purpose set forth.

ALFRED GAGE.
